Orangeish bownish edges on new growth leaves, HELP

Plant is about 5 weeks old and is a clone. 400W MH bulb and the top is roughly 8 inches from the plant. anyone know why the edges of the new growth have orange??????? Any input is appreciated

pics help, 8" seems close

yeah im thinking maybe heat stress but i worry its a nute deficiency

is it too hot at the top of your plants to keep your hand there? What's it growing in? Type of soil?

60% miracle grow 40% organic nutrient free soil a 2 gal pot and it is quite warm but not really too uncomfortable.. but maybe my baby is sensitive. i moved it down about 4-5 inches im going to see how it does from that...

a lot of miracle grow is time release nutrients, it may be too hot for your plant. Hard to say for sure without a pic. What's your Ph at?
